Description

Interactive electrolysis setup. Show a beaker with two electrodes connected to a DC power supply. Student chooses what to electrolyze: 1) Molten NaCl: At cathode (-): Na⁺ + e⁻ → Na (sodium metal deposited). At anode (+): 2Cl⁻ → Cl₂ + 2e⁻ (chlorine gas bubbles). 2) Aqueous NaCl (brine): Cathode: 2H₂O
